V-Core 3.1 Enclosure 2.0 500mm Belt Tension & Resonance Help

I'm trying to make out what these graphs mean and how to correct them. I rebuilt my toolhead out of PolyMax PC + heat inserts the other day along with made a revision to my EBB42 mount (in-front of LGX Lite). I'm planning on tearing down the printer to replace the PETG core components w/ PolyMax PC components over the next few days. I've been printing mostly high temp ASA, PA6-CF, PC functional prototypes with pretty good luck but want to make sure that I don't repeat something that I shouldn't when rebuilding. One belt tension graph was of the machine cold, after homing, and running z-tilt. Another belt tension graph was after heatsoaking the machine for about an hour (somewhat typical conditions as when I run a print). Ran Shaper Graphs for the heck of it to include. Although from what I gather, they are useless / not helpful if belt tension isn't correct. I'll work on getting a photo of the printer shortly V-Core 3.1 Enclosure 2.0 EVA 3 Bondtech LGX Lite Phaetus Rapido UHF BTT EBB42 (running hotend heater, thermistor, endstop, superpinda, hot end fan, part cooling fan)

I appreciate the input! I’ll be mindful when disassembling (to replace the printed parts) and make a list of what was loose.

Looks like your backplate is cracked.

That it does, I was so fixated on the belt that I didn’t even notice that. Nice spot! I’ll reprint the horns, fan duct, grabber and the housing that the grabbers go into (can’t think of the name) and replace them when I do the PC parts this weekend.
